After looking at the list on the Duet page I'm really leaning towards the piezo design.. can anyone speak to its performance and accuracy? ampapa,by ampapa - CoreXY Machines

Anyone have suggestions for a compatible probe for the Duet? I was looking at either, LJ18A3-8-Z/BX or LJ12A3-4-Z-BX...by ampapa - CoreXY Machines
Bare with me as I try to understand fully... So, currently I have 1 switch at the top of the Z axis. In this scenario, when I home the machine the switch is below the hot end and the Z axis is essentially set to Zero when it touches the switch. If I move the switch to be above the hot end obviously the hot end will bury into the bed before it zero's. So, I see 2 options then for homing the Zby ampapa - CoreXY Machines
I've been thinking about how to zero the Z axis and I must admit I'm a bit puzzled. I've done some searching but can't find any resources on how exactly this is accomplished.. On my CNC homing the axis tells the machine where 0,0,0 is and then I have to user a touch off plate to tell it where the top of the stock is. In the case of the 3D printer how do I tell it where the hot end is in compariby ampapa - CoreXY Machines

I've been running into most of the default settings for the online tool are not correct for my setup so there's a bit of a learning curve going on. Can anyone point me in the correct direction for information regarding setting up the extruder settings for steps, speed change, max speed and acceleration? Also, since this is a CoreXY setup is there a reason for the X and Y axis to be set to a difby ampapa - CoreXY Machines
Thanks Dave, that got me on the right track. When establishing the settings for the Extruder, if using a Bowden extruder and similar motors as my XY axis won't the setting be the same, steps, current, accel, etc.? Jsut seems odd that the config tool has the settings different... ampapa,by ampapa - CoreXY Machines
Thanks Dave. Does having the incorrect setting for the milliamps (mA) for the motor impact the actual distance the motor cover? Currently my settings for the motors are using 800mA but should be using 2000mA, I believe, so I'll make the correction. I have a 300mm x 300mm build plate and noticed the distance being covered according the interface is not currently correct 300mm doe not equal appx.by ampapa - CoreXY Machines
I'm about to wire up my E3D hotend and need to add a little wire to its length to connect to my Duet. I notice its fiberglass insulated, I think, do I need to use a specific wire type and terminals to extend the connection or can I use a traditional wire connector and wire? ampapa,by ampapa - CoreXY Machines

Very appreciative Deckigman, absolute and relative positioning throws me... The S1 command makes total sense and since I was just faced with some switch issues I can confirm the grinding and belt noise ;-( Once the machine has been homed will at any touch of a switch cause the machine to stop, fault as it will?

Thanks o_Lampe but I was hoping for a little more layman terms explanation than just the technical aspects. I mean, why change to G91 when homing? and why add an S1 on the end of a homing move? ampapa,by ampapa - CoreXY Machines
I was somewhat leaning towards PET... but I'm certainly open. So with an .250 heated aluminum build plate what is the recommended procedure for getting the first layer to stick? - glass on the plate - kapton tape - blue tape - glue stick - hairspray - etc.etc.by ampapa - General
I realize this question is up for debate and there are plenty of personal opinions but I'm looking for a good filament to learn with. PET and PLA in 1.75 I think are the best choices but maybe that goes without saying... Are there some manufacturers to avoid and others to gravitate towards? What about bed adhesion, are some better than others or is this more dictated by the material type? Is iby ampapa - General

Thanks DC42 for pointing me to the correct wiring. Will re-wiring the switch effectively operate it as a NC switch which I understand is the better approach? DjDemonD, that's what I'm seeing on the configuration tool description..by ampapa - General
I purchased some inexpensive limit switches without identifying their status as to NO or NC so I'm trying to understand how to tell the difference? While wiring up my DuetWifi I assumed the switches were NC switches but to my surprise they appear to be NO or did I mis-wire something? The DuetWifi board has a green light for the +3.3v as can be seen in the image below and I think that is a gby ampapa - General
Just to close the loop on this issue... posted from the Duet Forum. DC42, Thanks for your insight as ultimately the switch wiring and the machine properties page got me squared away. My newness overlooked that the Properties End Stop message said "EndStop Hit" was "yes" for all the axes.. Ultimately the problem was not that the switches were incorrectly wired, since the board had the 3.3v greby ampapa - CoreXY Machines
The homing process is still a flop.. not sure what's going on but certainly not making any headway. So trying to isolate the problem here by simply homing the Xaxis only, I assume this can be done on a CoreXY setup? ; homex.g ; called to home the X axis ; ; generated by RepRapFirmware Configuration Tool on Tue Nov 14 2017 17:05:20 GMT-0500 (Eastern Standard Time) G91 ; relativeby ampapa - CoreXY Machines
So using the configurator I made a bit of progress but I’m experiencing some issues with the limit switches. I believe the movements on each axis (300x300x325) are correct in length but the positioning within the axis is wrong. If I power on the machine and connect to it via the control panel what should I expect when I hit the home X button? I would expect that the x axis should move towards tby ampapa - CoreXY Machines
So I was following the guide at DuetWifi and there is no mention of commenting those lines out? CoreXY config When using the configurator what should be used for the steps per mm, is there a calculation to follow? For a newbie there are lots of questions that pop up when going through the configurator is it documented somewhere to be able to make decisions/choices? Thanks. ampapa,by ampapa - CoreXY Machines
The thing that's really puzzling is that all the steppers are moving when only a single axis should be moving. All the lights on the board appear correct and there was no magic white smoke on startup so... I was looking into the configurator, since I'm guessing that's where the problem is, and was curious why the Z axis by default is setup with 4000 steps and the XY are at 80, does that haveby ampapa - CoreXY Machines
First post to the forum so excuse the newbieness here.. So, I've just finished building and wiring my CoreXY and I'm using a DuetWifi board but I'm having a few setup issues in regards to setting up the steppers correctly or at least that's what I think the problem is. After modifying the config.g as recommended on the site DuetWifi CoreXY there is very little movement and all the axis seem toby ampapa - CoreXY Machines
I'm definitely not qualified to comment on the capability of the drivers and the stepping motion but I think from what I've read that anything above 16X is going to impact noise and not accuracy, I hope that's not an over simplification of the technical discussion above. Torque and holding power I think would be more critical in a CNC application and less in a printer application but that's justby ampapa - General
